私の名前はパヴェルです。
私は次のようなレイアウトを持ちたいです：
ボタンの数が変わるのでJavaでレイアウトしたい。四角はボタンです。以下で構成されるレイアウト:
<LinearLayout>
<Button/>
<TableLayout>
<TableRow>
<Button1/>
<Button2/>
</TableRow>
<TableRow>
<Button3/>
<Button4/>
</TableRow>
<TableLayout>
<Button/>
</LinearLayout>
私のコード:
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
int title = getIntent().getIntExtra(KEY, MainScreen.CHOICE_COMPUTER);
switch(title)
{
case MainScreen.CHOICE_COMPUTER:

break;
case MainScreen.CHOICE_LAPTOP:

break;
}
LinearLayout choiceLayout = new LinearLayout(this);
choiceLayout.setOrientation(LinearLayout.VERTICAL);
choiceLayout.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
choiceLayout.setPadding(15, 15, 15, 15);
choiceLayout.setGravity(Gravity.CENTER);
choiceLayout.setBackgroundResource(R.drawable.background);

日食のエラー:
09-21 12:41:09.062: E/AndroidRuntime(758): java.lang.ArithmeticException: ゼロ除算
柱を伸ばすことにつながっていると思います。
私の質問は次のとおりです: Androidでこれを修正して、写真のようにレイアウトを作成するにはどうすればよいですか?
